Chinese illustrator and anatomy instructor Chuan-Bin Chung encourages his students to understand the intricacies of the human body by drawing them. For many of his lessons he creates impermanent drawings on chalkboards as a helpful guide, but instead of quick sketches as one might be accustomed to, the pieces are exacting and colorful depictions of bones, muscles, and tendons—practically works of art in their own right. Chung shares many videos and sketches of his lessons on Facebook. (via Bored Panda)
